To find the percentage of a number, multiply the number by the percentage and divide by 100. Formula: Result = Number × (Percentage / 100).
200 × (15/100) = 200 × 0.15 = 30. So 15% of 200 is 30.
New Value = Old Value × (1 + Percentage/100). Example: 20% increase on 1,000: 1,000 × 1.20 = 1,200.
New Value = Old Value × (1 - Percentage/100). Example: 30% off 500: 500 × 0.70 = 350.
Percentage Difference = ((New - Old) / Old) × 100. Example: 80 to 100: ((100-80)/80) × 100 = 25% increase.
(30/120) × 100 = 25%. So 30 is 25% of 120.
